Chlorofluorocarbons, both of natural and industrial origin, currently exist as trace gases in the entire human environment. The CFCs cause ozone depletion in the stratosphere. Moreover, CFCs and SF_6 take part in intensification of the greenhouse effect. On account of international agreements, the measurements of CFCs and SF_6 in air were started. Measurement stations of these gases were situated at places outside of urban areas influence and gathered on the world-wide program - AGAGE (Advanced Global Atmospheric Gases Experiment). One of these stations is Mace Head (Ireland, 53° N, 10° W), which participates in AGAGE since 1987 and in InGOS (Integrated non-CO_2 Greenhouse Gas Observing System) program since 2011. Similar research is also conducted in Central Europe, in urban area of Kraków (Poland, 50° N, 19° E) since 1997. This work discusses the results of concentration measurements (1997-2012) of selected halocarbons and SF_6 in Kraków. To obtain concentrations of the measured compounds the mathematical procedure has been used, where concentrations were calculated using a five points Lagrange interpolation method. Daily arithmetic means of the measured mixing ratios and their standard deviations were determined. Based on these data, efficiency of Montreal Protocol legislation, implemented in Poland could be assessed.
